ATTACHMENT FOR INTERNAL-COMBUSTION ENGINES.

Application filed July 21, 1923, Serial No. 652,993. Renewed November 3, 1925.

To all whom it may concern. I

Be it known that I, MAURICE N. LEBECQUE, a citizen of the United States, residing at Tonopah, in the county of Nye, State of Nevada, have invented certain new and useful Improvements in Attachments for Internal-Combustion Engines, of which the following is a specification.

This invention relates to fuel saving attachments for internal combustion engines.

The object of the invention is to provide attachments whereby gases within the crank case of the internal combustion engine may be drawn into the intake manifold of said engine.

It is also an object of the invention that means he provided for thoroughly mixing the gases drawn from the crank case into the intake manifold or cylinder with heated and moisture laden air or steam.

Other objects, and objects relating to details of construction, combination and arrangement of parts will hereinafter appear in the detailed description to follow.

The invention is illustrated by way of example in the accompanying drawing, in-

which:

Figure 1 is a fragmentary view of the front portion of a motor vehicle and showing in side elevation an engine to which the present invention is applied,

Figure 2 is a detail View further illustrating the connection with the overflow pipe,

Figure 3 is a detailed sectional view illustrating the form of mixing valve employed in the present invention, and

Figure 4 is a detailed view illustrating the form of nozzle employed for introducing gases into the intake manifold.

Referring to the drawings more particularly in Figure 1, 10 indicates generally an internal combustion engine which is water cooled and provided with a radiator 11. At 12 there is indicated an intake manifold,

'' and at 13 a breather pipe which as well known communicates with the crank case of the engine.

In carrying out the present invention the breather cap has extended therethrough the one end of a pipe 14. This pipe carries a funnel 13 on its end within the breather cap. coupling member 15 is provided which is formed with the two outlet passages 16 and an outlet passage 17. This member also supports a valve member 18 which is provided with one inlet passage 19 and a plurality of outlet passages 20. This valve member may be referred to as a mixing valve and its specific purpose will later become apparent. The valve member 18 may be manipulated by a lever arm 21, said lever arm 21 having connected thereto a rod 22 and the rod 22 may be extended through the dash board of the motor vehicle and in position so that the same may be operated by the driver of said vehicle.

The outlet passage 17 of the coupling member 15 communicates with a pipe section 23 which in turn communicates with an L- shaped pipe section 24, said pipe section 24 being provided at its free end with an offset portion 25 which is formed with threads 26. The intake manifold 12 is provided with a suitable threaded opening adapted to receive the threaded portion 26 of the pipe section 24. The offset portion 25 of the pipe 24 is closed at its outer end, as at 27, and forward to the threaded portion 26 there is provided a plurality of small openings 28 whereby to form a spray nozzle.

The remaining passage 16 of the coupling member 15 is connected through a pipe section 29 and a hose 30 with a pipe section 31. The pipe section 31, is preferably bent as shown, and its free end is clamped to the overflow pipe 32 by the means of a U-shaped shackle or clamping member 33. The overflow pipe 32 for the radiator 11 is provided with a plurality of small openings 34, and these openings register with the associated end of the pipe 31.

The operation of the present arrangement is as follows: Assuming that the rod 22 has been manipulated to bring the valve member 18 in the position illustrated in Figure 4, then upon starting the engine the fumes within the crank case of the engine will be drawn through the valve member 18 and also after the water within the radiator 11 be comes sufficiently heated steam will be drawn from the overflow pipe 32 into the intake manifold of the engine. This steam together with the vapors from the crank case of the engine must both pass through the passage 19 of the valve member 18 and then pass through the passages 20 in said valve member. During this interval these gases and steam will be thoroughly mixed and upon passing through the nozzle at the inner end of the pipe member 24 the same will be further mixed. As is obvious the gases retrieved from the interior of the crank case will be introduced into the cylinders of the engine in a moistened and heated state. This moisture of the gases will lubricate the engine cylinder Walls and also prevent deposits ot carbon. Also considerable particles of oil are drawn from the crank case of the engine and thus the engine cylinders are further lubricated.

I claim:

An attachment of the character described comprising a pipe section having a threaded portion at its one end adapted to be threaded through an intake manifold of an internal combustion engine, a spray nozzle carried by the last-named end of the said pipe section, a Y coupling supporting a mixing valve carried by the other end of said pipe connection, pipe extensions carried by the Y coupling whereby the overflow pipe of an engine cooling system and the interior of the engine crank case may be brought into communication with the intake manifold.
